Optical fiber networks are based with various passive optical networks (PON) standard. A PON is a networking that is specifically designed for fiber technology, which provides broadband network connectivity to your business or home. One of the PON specifications is GPON.
The term GPONstands to mean Gigabit Ethernet Passive optical network (PON). GPON utilizes the Asynchronous Transfer Mode (ATM) in order to voice communications, Ethernet for data, and a proprietary encapsulation method for voice. This means it utilizes fixed-sized cells, not variably sizeable packets of data. It provides speeds that are faster Gbps that EPON (Ethernet active optical network) for both upstream and downstream bandwidths.
A GPON system is made up consisting of an optical line terminal (OLT) that connects multiple optical network terminals (ONTs/ONUs) with an optical distribution network (ODN).
The GPON can support:
- Triple-play services (VoIP Data, IPTV and VoIP) that offer an all-services solution that is competitive and competitive.
- More data rates and faster transmission
- Long-reach coverage
- Data encryption and security enhancements (supports block lengths of 128 bits as well as keys with lengths of 128,192 as well as up to 256 bits.)
- All kinds of Ethernet protocols.
GPON provides:
- High-quality of service (QoS)
- Dynamic bandwidth ability to allocate bandwidth
- Flexibility
It is a preferred choice with major telecom providers across the globe. Because GPON allows you to integrate multiple services onto one fibre transport system, this is one of the reasons why people choose GPON over other options.
GPON basics and how it operates:
GPON is a point to multipoint access network. The primary characteristic of GPON is the fact that it utilizes passive splitters within the fiber optic distribution networks (ODN). This allows one feeding fibre from an Internet service providers (ISP) to be used by several households or businesses. A fiber optic is the term used to describe the way in which fiber technology makes use of cableto transfer the light.
In this case we’ll use an optical line terminal (OLT) located at the Internet service provider (ISP) headquarters the GPON system’s starting point.
- The Internet as well as voice/telephone as well as TV’s data service your ISP offers are delivered from this point on.
- The data is transported along an optical distribution system that is single-fiber (ODN) up to the optical splitter.
- Once the data has reached the splitter, it divides the light signal into several signals that are distributed to each ONT/ONU device on your home premises or your company to allow you the ability to access these facilities. The ONT/ONUs are the ending point(s).
The steps are as follows:
OLT sends one-point signal ODN splitter breaks up into multiple signals. Multiple ONT/ONUs receive signals.
The following is an elaborative version however, it provides an idea of the basics of what’s happening in an GPON system.
GPON gives you a broad variety of benefits that allow quick, flexible, mass-market fiber deployments with the most affordable cost of the ownership and rollout. Contact you ISP for more information about Smartnet options today.
